WHEEL.

SPECIFICATION forming part of Letters Patent No. 514,360, dated February6, 1894.

Application filed March 20, 1893. sis-in No. 466,952. on model.)

To all whom it may concern.-

Be it known that we, VVILLIAM GRAYSON and LOUIS J. OREoELrUs, both ofthe city of St. Louis, in the State of Missouri, have invented a certainnew and useful Improvement in Wheels, of which the following is afull,.clear, and exact description, reference being had to theaccompanying drawings, forming part of this specification.

Our invention relates to an improved wheel for tricycles, velocipedes,wagons, baby-carriages, &c., and the object of our invention is toproduce such a wheel with ball bearings, in which the balls are retainedin enlargements at each end of the sleeve of a hub, and yet projectsufficiently into the spindle cavicy so as to bear upon the spindle towhich the wheel is applied, so that when shipped from the factory, noadjustment of parts is required, and the wheel can be put into use bysimply slipping it onto the spindle, as with an ordinary wheel, and atthe same time to construct such a wheel so that the balls will heardirectly upon the spindle at right angles thereto.

Our invention consists in features of novelty hereinafter fullydescribed and pointed out in the claims.

Figure Iis an elevation, illustrative of our invention. Fig. II is atransverse section, taken on line II-II, Fig. III. Fig. III is an axialsection, taken on line IIIIII, Fig. I. Fig. IV is an elevation. Fig. Vis a detail section, showing one form of a ring for holding or retainingthe balls in position. Fig. VI shows a modified form of the ring forholding the halls. Fig.VII is an elevation, illustrating a difierentform of the invention from that presented by Figs. III and IV.. Fig.VIII is a longitudinal section of the form represented in elevation byFig. VII. Fig. IX represents still a difierent form of the invention.Fig. X is an axial section showing the form of ring illustrated in Fig.VI located within an enlargement of the hub.

Referring to the drawings, 1 represents enlargements of the hub of astaggered wheel, to which the spokes 2 are secured, in any suitablemanner. The enlargements 1 are connected by a sleeve 3, which, in theform shown in Fig. III, extends a short distance into the sockets of theenlargements to form innerside supports for anti-friction balls as shownat i.

5 represents the anti-friction balls fitting in the enlargements 1, andretained therein bya suitable encircling bearing ring 6. We

' have shown this ring having a retaining flange 7, of slightly dishedshape, providing an inturned inner margin which in connection with theslight extension dot the sleeve 3 holds the balls loosely in place, andkeeps them from dropping out before the wheel is placed on the spindle,upon which it is designed to'be used. The ring fits snugly in theenlargement, with sufficient friction to prevent it from dropping out.

In Fig. VI we have shown the ring provided with two slightly dishedretaining flanges 8. In this form the balls are inserted in the ring andthen the inner edges of the retaining flanges are turned or slightlydished inwardly to retain the balls in place, and the ring containingthe balls is then inserted into the enlargement as shown in Fig. X.

In Fig. VIII we have shown the sleeve of the hub cast in one piece withthe enlargements, and have shown the ring 9 with a slightly dishedflange 10, which in connection with the slightly dished ends 11 of thehub, holds the balls in place.

In Fig. IX we have shown the retaining flange 12 associated with a ringl2 located on the hub within the enlargement. In this form the retainingflange is slightly dished, as shown, and in connection with the slightlydished end 13 of the hub holds the balls in place. The halls extendslightly into the spindle cavity of the hub, or slightly beyond theinterior face of the hub, so that when the wheel is placed on thespindle, the balls will bear directly thereon at' right angles to thespindle, thus avoiding the use of unnecessary parts and unnecessaryfriction.

Our wheel is designed to be used on any spindle of the proper size toreceive it, and does not difier in this respect from an ordinary wheelwithout ball bearings.

Having thus described our invention, the following is what we claim asnew therein and desire to secure by Letters Patent:

1. A wheel provided with a hub constructed with an enlargement at eachend, asleeve connecting the enlargements, spokes secured at their innerends in said enlargements, antifriction balls projecting into thespindle cavity and bearing rings en circling the balls, each ring havinga retaining flange formed with an inturned inner margin for holding theballs in position, substantially as described.

2. The combination of thehub enlargements 1, 1, connecting sleeve 3,spokes 2 secured in said hub enlargements, anti-friction balls 5protruding within. the spindle cavity of the hub, and rings 6 encirclingthe balls 5, affording radial bearing thereto and each ring hav- 5 ingtwo inturned flanges 8, 8, which retain said balls within the hub, asexplained.
